BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a plug connector, and particularly to aplug connector capable of making a propping lid detachably mounted to aninsulating housing so as to make soldering tails of terminals solderednot only cables but also a PCB (printed circuit board).

2. The Related Art

A conventional plug connector includes an insulating housing, aplurality of terminals disposed in the insulating housing and havingsoldering tails projected behind the insulating housing, a shieldingshell enclosing the insulating housing, and a propping lid mounted at arear of the insulating housing. Generally speaking, the shielding shellis coupled with the propping lid to make the propping lid, the shieldingshell and the insulating housing secured together. The soldering tailsare against a top and a bottom of the propping lid so as to be solderedwith cables. However, the foregoing plug connector only is adapted forconnecting with the cables, because the propping lid is secured with theshielding shell to always prop the soldering tails. When the solderingtails need to be connected with a PCB, another plug connector withoutthe propping lid is required.

SUMMARY OF THE INVENTION

Accordingly, an object of the present invention is to provide a plugconnector. The plug connector includes an insulating housing having abase body and a tongue portion protruded forwards from a front of thebase body, a plurality of terminals disposed in the insulating housing,a shielding shell having a casing for surrounding the tongue portion ofthe insulating housing and a rear coupled with the base body of theinsulating housing, and a propping lid. A rear surface of the base bodyis provided with a plurality of insertion holes spaced from one anotherand each concaved forward. Each of the terminals has a soldering tailprojected beyond the rear surface of the base body. The propping lid hasa base block mounted against the rear surface of the base body, and aplurality of insertion bolts protruded forwards from a front face of thebase block for being inserted into the corresponding insertion holes ofthe base body to make the propping lid detachably mounted to theinsulating housing. The soldering tails of the terminals can be solderedwith cables respectively by means of being positioned against a top anda bottom of the base block, or directly soldered onto a printed circuitboard by means of demounting the propping lid from the insulatinghousing to set the soldering tails free.

As described above, the propping lid has the insertion bolts protrudedfrom the base block to be inserted in the corresponding insertion holesof the insulating housing, so as to make the propping lid detachablymounted to the insulating housing. Such structures make the solderingtails of the terminals capable of being soldered with not only thecables but also the PCB, by means of mounting the propping lid to therear of the insulating housing to position the soldering tails ordemounting the propping lid from the insulating housing to set thesoldering tails free. So the plug connector can be widely used inelectronic products to meet different demands.

A wedge 17 is formed at a centerof each indentation area 16. A bottom of the tongue portion 19 defines aplurality of terminal grooves 11 arranged at regular intervals along atransverse direction thereof and each extending longitudinally topenetrate through the base body 18. The insulating housing 10 furtherdefines a pair of receiving slots 12 located at two outmost sides of theterminal grooves 11 and each extending longitudinally to penetratethrough the base body 18 and the bottom of the tongue portion 19. A pairof fastening cavities 14 is opened at substantial middles of twoopposite sides of the base body 18, and each extends longitudinally topenetrate through the front surface of the base body 18. A locking bump15 protrudes at each of the fastening cavities 14. Two opposite ends ofa rear surface 181 of the base body 18 are provided with a plurality ofinsertion holes 13 each concaved forward with a diameter thereofgradually shortened.

Referring to FIG. 2 again, the shielding shell 30 has a rectangularcasing 35 for enclosing the tongue portion 19 of the insulating housing10 therein. The casing 35 has a top plate 36, a bottom plate 37 facingthe top plate 36, and two opposite side strips 38 connecting the topplate 36 and the bottom plate 37. Middles of rear edges of the top plate36 and the bottom plate 37 are oppositely bent perpendicularly to thetop plate 36 and the bottom plate 37, and then extend rearwards to forma pair of buckling slices 33. A buckling opening 34 is opened at acenter of each of the buckling slices 33. Each of the side strips 38 iselongated rearwards to form a clamping arm 31, with a locking hole 32being opened therein. The propping lid 40 has a substantiallyrectangular base block 43 and a plurality of insertion bolts 42protruded forwards from two opposite ends of a front face of the baseblock 43. The insertion bolt 42 is of substantially columned shape andgradually thins in diameter along the extending direction thereof. A topand a bottom of the base block 43 respectively define a plurality ofpositioning fillisters 41 arranged at regular intervals and eachextending along a front-to-rear direction to penetrate through the baseblock 43.

Referring to FIG. 1, FIG. 2 and FIG. 3, in assembly, the terminals 20are disposed in the corresponding terminal grooves 11 of the insulatinghousing 10 and have soldering tails 21 thereof projected beyond the rearsurface 181 of the base body 18. The latches 50 are inserted forwards inthe corresponding receiving slots 12.
